kApplication led September 21, 1921. Serial No. 502,168.y

This invention relates to tank cars, yand it has specialreference totankcars in which thetanks are carried attheir ends upon suitable supportsand are anchored'to the car jury. to the-tanks and v'rivets is likely,ac-v 1 companied by Y .consequent leakage of the vtank contents.. Thesestrains and stresses result either from inaccurate alignment of the endysupports with the kcenter anchorage, or from the. wear. of `theend+supporting blocks under. conditions of use, thereby permitting .thetank to settle, rand imposing undue f weightnpon-the center anchorage.

[Accordingly, one yofthey objects of the presentinvention is to providela tank car of the above-indicated character, lwhich'shall. embody,intermediate the end supports, 'a'

tank anchorage which is so constructed and f arranged as'toprevent'bodily-longitudinal 'shifting movements of the tank and at thesame time be capable of yielding vertically to a.v certain extent, sothat the wei ht of AVVthetank is'always carried bythe 'en supdate itselfto any irregularities in'theali'gn- 'nient' of the end supports or tothe wear of Athe supporting end blocks. lhe tank 'agnchorageofthe'present invention, therefore,`

is not intended to support the tank butmerely to tie the tank rigidly tothe underframe 'and to yield vertically to 'a' suiicientextent devicesare fastened and shaped in such ymanner as to embody pronounced loopskor bends, probably having reversed curved undulations in the respectivelegs thereof which serve to `lend a 'certain amount of yielding or:resilience in a verticaldirection for the abovef-indicated purposes.

` 4 Anotherlobject ofthe `invention is t-o provide a structure of theabove-mentioned type j 'which isi provided withv a discharge outlet.pipe or` pipes projecting laterally from beneath the tank vandembodying a lvalve or .valves and suitable operating mechanisms thereforthat are located at the side of the,

car where they are conveniently accessible to vices preferably comprise.two sets of tie members such as already. described, which are slightlyspaced Vapa'rtin a longitudinal. direction to permit the dischargeoutlet pipes, valves and operating mechanisms to be convenientlylocatedin the space between them.

- The invention willbest be understood from the following descriptionofthe accompany- `be handled. Accordingly, the anchorage deingvdrawings, wh'ich illustrate a preferred embodiment y'of the inventionand in which Fig. 1 is aview in sidey elevationfof a tank ent invention.Y

Scar constructed in accordance withthe' pres- Fig. 2 is an enlargeddetail-view of aportion of the structure sho-wnin Fig. l, illus-vtrating particularly the constructionand location ofthe anchoragedevices and the controllable discharge outlet pipes.v

"Figi 3 is a sectional view'along the section `Fig. 4 is ya sectionalview along thesection line lr-'4 of Fig. l.

Referring vto` thedrawings, lthe structure illustratedvr comprises, ingeneral, a plurality of trucks 10 -vuponwliich an underframe 1:1 isvmounted, the underfianie being provided with end supportingfsaddl'es'12having wear blocks secured thereto fo'r supporting anY lelongated tanklil latfits respective ends. .The weight of theI tank iscarried`substaie tially entirely by the-wearfl blocks and end saddles, -andthe' tank 'is 4rigidly tied ,to the underframe to anchorit againstbodily'longitudinal movements loyme'ans'of` anchorage devices 15, whicharerigidly secured to the tank and'to the underframe, and fw'hicliaieslightly spaced apart tov provide "room, Orf a plurality o-f laterally`projecting' discharge Voutlet pipes `1'6,fa1valve 17 and Va-laterallyprojectingjoper'atingmechanism 18. f' v The trucks 10ni`ay be of-'anysuitableaiid well-known construction and l`are adapted to lcarry orsupport vrt-he underfranie "11'.`in-ac cordance with customary practice.iT-he kunderframe llnmay constitute a singlejlon-L gitudinally extendingcenter silll, fasfzillus-v trate'd in the '-draw'ings, or, ifdesired,ajfplurality of flongitudinal sills may be employed.

The f center 'sill illustratedcomprises a =plurality of longitudinallyextending and vertically disposed channel members 2O to which aresecured horizontal plates21 and 22 to form a substantial unitarybox-.like structure. Near eachend of the sill is a supporting structure23 projecting laterally in oppositel directions therefrom, and therespective arms of each yof these structures are provided withV V-shapedmembers 24,

-each pairofwhich constitutesan end saddle 12. The V-sliaped members 24of each set of Aend saddles vare inclined Vinwardly toward the centerline of the car underframe and are provided lwith a Vplurality oflongitudinally disposed wear blocks. 13, which vare suitably securedthereto, lthespace between the respective vmembers 24 of each set beingalso filled with .wear` blocks 13. These wear blocks are preferably ofwood or other suitableinaterial andthe upper surfaces thereof are shapedto conformto theiconfiguration of the tank 14 so that the tank may restY Preferably these devices comprise two sets of oppositelydisposedtiemembers or `plates whichare f ormed inthe manner Shown in Fig. 3,the-two sets lbeing slightly spac-ed apart for the purposes already,mentioned The anchorage members of eachl set are placed on oppositesides of the tank center line and are in the preferred embodimentof theinveiition, located substantially midway between the endsof the gtankbuttheir .location fis not so restrictedand, in fact, additional sets ofanchorage devicesmay be employed, as lindicated, forinstance, in dottedlines in Fig. 1, to ywhich the ,reference nu-l meral v15ZL is applied.The tie members 15 may conveniently be made of-.metal plates which arebent into such form as'to provide pronounced bends 27, or vthey may becast, forged or otherwise constructed, so long as they are yielding orresilient ina vertical direction.l These plate-s :are rigidly andtightly secured by means ofrivetsr28 to the tank 14and also -to theAprojecting ianges .29 of the center sill l1 by means of rivets 30.

Thel function ofthe bends 27, Vas yalready stated, is topermitof acertain degree ofV vertic-al yieldingin order to avoid imposing upontheitank or the attaching rivets undueV stress or strain which mightresultfin shearing-the rivets and rupturing ,the tank with theconsequent leakage of the tank contents. This resilient oryielding-element in the anchorage devices is of especial importanceas itpermits the tank to laccommodate itself to irregularities in thealignment of the end saddles .and vsupporting wear blocks which mayresult either from inaccurate assembling or from wear ofthe blocksrunder 4conditions of use. rllhis `character of anchorage, therefore,permits of some latitude in the :positioning of Athe saddles V.and wearblocks yduring assembling, and furthermore, allows the tankto settle toquite an appreciable .extent due to y'the wear of the support-V ingblocks without imposing. injurious strain upon the tank or 4the.attaching rivets `28.

Furthermore, slight transverse shiiftingfor V rocking movements of thetank are permitted without detrimentaleifect. The anchorage devices .15,however, are :substantially rigid ina longitudinal direction and preventbodily movement of the tank. Absolute ri'- gidity is not necessary, orin fact desirable, as there may beslight eloiigations forfcontractionsofthe tank `between the two -set-s of anchorage -devices due to`.temperature changes. Such variations, ofcourse, are. eX- tremelyfslight, onaccountoif-the short length of the space .and are,.:therefore,almost. inappreciable. However, `the configuration of Y the anchoragesor :tie members is such :that

these slight changes :may befaccommodated without the developmentofundue :strains,

and Iinjury that may result therefrom. f

The respective Alegs of each of fthe pronnounced loops kor bends i ofVthe anchor aplates are preferably provided with reversefcunvedundulations as clearly illustrated .in r`Figure 3 of :the drawings.y Theobject/'of theseinndulations is to lend increased resiliency orcapability of bending to the anchor plates,

whereby undesirable stresses. ;in the plates under operating Condit-ions.are `eectively eliminated. Y nFor the purpose ofwithdrawingthegcoiitents of the tank, the tank is provided with aplurality ofl .outlet l.discharge pipes 16 vwhich project laterallyinoppositedirections frointhe valve ,17,whichis attached to the bottom ofthe ita-nk and.co'mmunicatesftherewith. rFliese discharge pipes 16 andvalve17 are Hlocated intermedi atev they two spaced sets',v

fof anchorage devices 15,. The valve '17 :is

provided-with an operating-handle or mechanism 18 which also projects4laterally through the space .between the anchorage devices and intopositionzwhere it-,is readilyVlr accessible to the operator.,ltispreferablexto provide the respective discharge Ipipes 16 withindividual control valves 1"("2,` 1

Obviously the structural details shownand described maybe .modifiedgreatly while-1i'- still retaining the advantages ,and benefits of theinvention. The scope of the invention, therefore, should not berestricted in any sense to the particular illustrative e1nbodi-`ment'set forth, but is defined in the appended claim.

Having set forth the nature and described a preferred embodiment of theinvention what is claimed as new is:

In a tank car, the combination With a supporting frame, tank supportsmounted at the ends thereof and a tank restingupon and carried by saidsupports, of a plurality of closely adj acenty anchorage devicesdisposed intermediate the tank supports and rigidly secured to said tankand said underframe for preventing bodily longitudinal movements of saidtank, a plurality of discharge outlet pipes communicating With said tankand projecting laterallythrough the spacey between said anchoragedevices, a valve for controlling 20 said outlet pipes and operatingmeans for said valve'projecting laterally through the space between saidanchorage devices.

In Witness whereof, I have hereuntoset my hand this 17th day ofSeptember7 1921.
